The next illustration shows the “Franchise Transmedia” project. It’s a series of single-platform deliverables – a book, a movie, a game. In many ways the platforms are independent except that they often cover different narrative spaces: prequel, sequel, flashback which may dictate a release order or schedule. In any case there’s no apparent audience interactivity between the platforms.

Portmanteau Transmedia project, by contrast, might look like an Alternate Reality Game (ARG) which will often cover a single narrative space across multiple platforms – each alone insufficient to carry the complete story but like jigsaw puzzle pieces they must be assembled to complete the picture.
